To all 'whom 'it may concern:

Be it known that l, ALirnnn ill. loovnns, a citizen or" the United States, residing Brooklyn, in the county of llings and State of New York, have invented certain new and useful improvements in Coin Controlled Electrical Apparatus, oi which the following is a specification.

lily present invention pertains to improvements in coin-controlled electrical apparatus, the construction and advantages oi which will be hereinafter fully set forth, reterence being had to the annexed drawings wherein Figure 1 is a rear elevation of the apparatus, the door which is employed to close the casing being omitted; Fig. 2, a similar view, the coin having been introduced, the parts locrred together thereby, and the handles which the user grasps being dravm down Fig. 3, a side elevation of the mechanism, the casing being shown in section; Fig. l, top plan view ot the mechanism; 5, a detail sectional view one of the handles; Fig. 6, a transverse sectional view, on the line 6 6 oi Fig. 5; Fig. 7, an elevation oi the clock mechanism, the traveling' contact finger and the member which receives the coin and also positions the contact linger; S, a vertical sectional view, on the line 8 8 ot Fig. 1,' Fig. 9, a detail perspective view of the contact linger; Fig. 1G, a perspective view or the plate which carries the coin-receiver, the arm which resets the contact finger, and also carries and moves the arm which throws the spring contact plate out of contact with the traveling finger; Fig. 11, a detail perspective view of a portion ot the casing,` Fig. 12, a similar view or" the supporting frame for the mechanism 3 Fig. 13, a 'front elevation of the cabinet, showing the actuating handles and the indicating mechanism lfig. 14, a rear view oi' the rotatable indicating disk; Fig. l5, fr view of the same Fig. 16,

The main object ot the present invention l l l I l i l l l is to provide a simple and eilicient means for controlling the secondary circuit, whereby `.he ilow or' the current is graduated and the iassage of the full volume or the current preented at the beginning of the operation, yhe increase being gradual and under absoute control of the user of the machine.

further object is to provide two movable handles, so connected that they move in unison, one handle being Ainsulated from the other.

il. further object is to provide an accurate and attractive indicating mechanism., whereby the extent oi movement oi the handles, and consequently the strength of the current passing therethrough and through the user, will be indicated.

fr further object is to provide a construction whereb f' the mechanism may be completely assembled and while in such condition introduced into the cabinet and secured thereto.

lff ith these and other objects in view l will now proceed to a detail description of the apparatus.

'lhe cabinet, designated by A, is mounted upon and secured to a casting E, Fig. 13, which in turn surmounts a column or pedestal O, though olE course the cabinet may be placed in any desired position.

The front face of the cabinet is provided with a circular opening, ligs. 3 and il, the edge being rabbeted or formed with shoulder i), see lFig. il. Extending downwardly from said circular oper is a recess lll, the lower edge of which is deiined by two semicircular recesses F, which form seats for the rubs or cylindrical bearings G and ll, eX- tending outwardly from. the main trame or casting l, upon which the mechanism is mounted. l he traine is provided with laterally extending lugs J, l and L, Figs. l2 and 18, through which screws are passed into the rear side of the front of' the cabinet, other screws (see Fig. 1) being passed through the body of the trame into the cabinet.

A circular plate ll, preferably oi' tin and having a sheet of paper secured to it, is iastened over the opening in the iront oi the cabinet and rests against the `shoulder D. Said plate, as will best be seen upon reference to Figs. 13, 16 and l?, is provided with a spiral opening or slit N, the inner end of which terminates in a heart-shaped 'ligure O, printed, preferably in red, on the plate The central portion oi the plate will preferpreferably ably be supported by integral cross-pieces 2 and Q, and said plate will also by preference be provided with two oppositely-disposed series of small openings R and S.

Secured upon a disk T and in rear of the plate ivi is a second rotary or oscillatingplate U, said plate being provided upon its face with a substantially spirally-disposed blue Zone V and with a red Zone NV, the Zones occupying such positions that when the handles are elevated, or when the operative mechanism is not locked thereto, as will hereinafter appear, the blue zone underlies the spiral slit N and the red Zone appears beneath the series of openings R and S. When, however, the handles are connected to the operative mechanism and the plate or disk U is caused to revolve to a greater or less extent according to the degree to which the handles are depressed, the red Zone will be exposed, appearing first at the inner or heart-shaped end of the slit, and gradually extending until, if the handles be fully depressed, entirely underlying the slit. At the same time the blue field or Zone `V will gradually pass away from beneath the series of openings, being replaced by the red. Plate U also carries an indicator or pointer X, Figs. 15 and 16, which normally underlies the cross-piece l), so as to be hidden from view. Said pointer passes adjacent to a series of numbers, say from 0 to 1000, arranged adjacent to the edge of the upper portion of the spiral slit. Thus one can secure a relatively accurate measurement of the current taken at diiierent times. Disk T is secured upon the outer end of shaft Y, which is mounted in the supporting frame or casting l and in an overhanging bracket Z formed at the upper end thereof, see Fig. 8. r.lhe indicating mechanism thus constructed and the opening E through which the hubs are passed in the act of assembling the machine are covered and protected by a faceplate or casting A', which is formed with a central opening in which is mounted a glass plate B. Casting A is also provided with a series of depending fingers C' which pass between and to each side of the hubs G and H and thus covers the entire front of the mechanism. Screws are passed through the outer fingers and into the casing, and tap-screws B (F ig. 1) are passed from the inside of the casing into lugs formed upon the upper portion of the faceplate.

E and F represent the two handles which are grasped by the user and depressed from a normal horizontal, at varying degrees, to a substantially vertical position. Stem or axle G of handle E',s'ee Fig. 18,has securely pinned to its inner end a casting comprising downwardly-extending arm H', upwardlyextending arm l and a gear or toothed section J a spring K being secured to the lower end of arm H and serving normally to draw the arm toward the adjacent side of the cabinet, or in other words to throw the upper arm l over toward the center of the machine, at which time the handles will occupy a horizontal position.

handle li is insulated from trie metallic framing of the machine and is constructed, preferably, in the manner shown in lligs. 5 and 6. The handle proper is provided with a reduced end which is seated in an insulating bushing L', the end and bushing being secured to the angular socket-piece M' by a fiber through-pin N. The angle piece in turn is secured to an axle or stem O' which is seated in the hub il. Pinned to the stem or aille is a casting or member comprising a lower arm P' to which is secured a spring Q serving to draw it outwardly, an upper arm l', which under he stress of' the spring is thrown over and into contact with the rubber bumper S carried by arm l' and a coinarresting and locking arm T. The casting or member is also provided with a gear or toothed section U which meshes with gear 5, whereby both handles must of necessity move in unison, and by reason of the action of the springs will normally occupy a hori- Zonta-l position. Loosely journaled upon stem O is a hub V which carries or has formed therewith a plate W' best shown in Fig. 10.

'lhe plate carries an arm X having an inturned end Y', which, with the simi ar end Z' of a pivoted arm A2, forms a temporary abutment against which the coin may be pressed by the upper end of the arm T', the. coin at such time being held against vertical or edgewise movement by the finger B2 extending from the arm T', see Figs. and 18. Arm A2 is pressed over toward arm X' by a spring C2, and is prevented from swinging too far by a stop-finger A* which comes into contact with the arm X', thereby holding the finger-piece D2, which is formed as a part of arm A2, a slight distance from the fixed arm or stop E2. rlhus it v. ill be seen ico that when a coin is introduced into the mawith a downwardly extending finger or arm l2 which stands in line with the forward sharp edge of the coin-locking finger or arm T', see Fig. 3. l/'Vith a coin in lace, a downward movement of the hand es will cause a correspondincy rocking movement of the plate W, the plate moving back and forth with each and every movement of the `handles until such time as the coin may be secondary winding to screw U3, block la, contact screw F3, vibrator G3, to frame or casting l and to the uninsulated handle E.

To regulate the intensity of the induced current l provide the following means: Surrounding the induction coil is a metallic sleeve or tube-V3, preferably vof brass, about which is wound a wire "4i-f3, the ends of which are connected to each other, or to the tube. This tube with its winding is designed to be moved back and forth over the induction coil winding and acts as a damper or regulator to control the intensity of the induced current. rlhe sleeve is provided with a downwardly-extending bracket or plate X3, having a slot YB formed therein. Plate W is provided with an upwardly-projecting arm Z3, and a link .d4 is pivotally connected thereto, the opposite end of the link carrying a. pin which extends through the slot, the connection permitting a slight forward movement of the plate W independent of the sleeve. As will be readily seen, the farther the handles are depressed and consequently the farther the plate W is rocked, the more the tube will be withdrawn from over the coil. rllhe intensity of the induced current increases as the tubular member is withdrawn from the coil, and inasmuch as its position is regulated by the depression or raising` of the handles, the amount of current which will pass through the handles is at all times under the control of the user. rihe direction of current may be changed by simply shifting the battery connections.
